MULTIPLE PACKAGE Leroy L. 'Salshergy South Orange, N. J., assignmto Ivars-Lee Company, Newark, N. J., a corporation of Delaware Application April 26, 1939, Serial No. 270,0791/2 6 Claims. (Cl. 206-56) 'liiis invention relates in general to packages ior unit products such as medicinal or chemical tablets or pills, buttons or other small articles.

ltfiore` particularly the invention contemplates p such a package that comprises a strip or tape ol packaging material either thermoplastic or having .a thermoplastic or adhesive coating, ior eliample, flllioiilrn, Kodapak" Protectoid,M Diaphane or thermoplastically or adhesively coatip ed cellulosic sheet rnaterial such as Cellophana or rnetal ioil, said strip or tape having a plurality oi. spaced article holdiing;F compartments.

The strip niay be iorined by :foldingr the inaterial into superposed layers or by superposing nl separate layers; the articles are disposed be" tween the layers and the superposed layers are pressed iiatiy together and sealed in adhering contact with each other between adjacent articles so as to hold the articles in spaced relation ppand completely close the compartments.

strip is bent or iolded between adjacent com partrnents into zigzag iorm or divided, so as to iorin a plurality oi preferably rectangular secl tions in side-by-side relation with the hat poriid tions interposed between the juxtaposed coinn pp into and removed from a carton and the articles conveniently individually removed without possibility oi unintended folding oi the strip.

another object is to provide a package oi the character described wherein the material ci the ,m edge strip shall be folded in a novel and iinproved manner to provide extensions on the sec tions and the extensions caused to adhere to each other to releasably hold the sections in side-byside relation or the strip in zigzag folded condi-- im tion.

other objects are to provide such a package embodying novel and improved features of construction whereby a label can be applied directly to the package; and to obtain other advan lid tages and results as will be brought out by the following description.

For the purpose of illustrating the inventionI have shown it embodied in several different forms 'in the accompanying drawings, but it should be di understood that this is primarily for the purpose of illustrating the principles oi the invention and that many modifications and changes in the form and structure of the package embodying the invention may be made without departing from the spirit or scope oi the invention.

Specifically describing the embodiment of the invention illustrated in Figures 1 to 8 inclusive, the package includes a strip or tape A formed of suitable' thin material either thermoplastic or having a thermoplastic or adhesive coating, for example Plioiilm," Protectoid," "Diaphane or thermoplastically or adhesively coated cellulosic sheet material such as Cellophane" or metal foil. The strip comprises a plurality of superposed layers I and 2 which may be formed by folding a strip of material longitudinally as at 3. Between the layers l and 2 are formed a plurality of compartments 4 for containing articles such as medicinal tablets 5, the compartments being in Vspaced relation longitudinally of the strip. One

side of each compartment 4 comprises the fold 3 oi' the strip, while the other three sides are formed by crimped and sealed areas 6 extending transversely of the strip and a sealed area 1 extending longitudinally of the strip along the free edge portions of the layers.

Where the strip of material is thermoplastic or has a thermoplastic coating on the contacting surfaces of the layers I and 2, the sealed areas 6 and 1 may be formed by simultaneous application of heat and pressure to fuse the material. The crimping may be of any suitable form such as the longitudinal corrugations illustrated.

The package strip after having been formed as described with the articles encased therein, is folded or bent transversely between the compartments 4 as indicated at 8in Figure 4 so as to forma plurality of approximately flat sections disposed side-by-side with their general planes in opposed approximately parallel relation to each other and with two rows of articles 5 and a crimped and sealed portion 8 between each two adjacent articles as clearly shown in Figures 4 and 5.

The longitudinally sealed area. 1 constitutes an extension of the packaging material along one edge of each section as shown in Figure 5, and in accordance with the invention the extensions 9 of adjacent sections are folded and separably secured together as shown in Figures 6, '1 and 8. The extensions may be so secured together adhesively and preferably by thermoplastic adhesion, so that the extensions may be separable from each other for removing the articles from the package.

With this construction, it will be observed that the sections of the package are held together as a unit so that the package can be handled and inserted into and removed from a carton, and the articles individually can be conveniently removed from the package without possibility of unintended separation of the sections or unfolding of the strip. To remove the articles from the package, the extension 9 of the end-most section is pulled away or separated from the extension of the adjacent section so that the section can be unfolded. Then the material of the strip may be torn transversely adjacent the article 5 so as to open the compartment 4 and permit removal of the article.

Another form f package strip is shown in Figures 9 and 10 where a strip of material has its edge portions I0 and II folded inwardly into overlying relation to each other and secured together, preferably 'thermoplastically. Article containing compartments i2 are disposed in spaced relation longitudinally of the strip with crimped and sealed areas I3 extending transversely of the strip'between the articles. One or both longitudinal edges of the strip may be an extension I4 which may also be flattened able material which are secured together along each of their longitudinal edge portions as at I1. Article containing compartments I8 are spaced longitudinally of the strip with crimped sealed areas I9 between-the compartments. Preferably the distance between each of the compartments I8 is substantially equal to the width of the compartment so that the strip may be folded transversely in zigzag form as described in connection with Figures 1 to 8. The longitudinal edge portions I1 form extensions on the sections between the folds, and the extensions of adjacent sections are folded into overlying relation and separably secured to the extensions of adjacent sections as hereinbefore described.

Figures 16 to 18 inclusive illustrate another form of package wherein the package strip has a plurality of article containing compartments v 20 disposed in spaced relation longitudinally of the strip with flattened, crimped and sealed areas 2| between the compartments. 'I'he strip is folded into zigzag form transversely at Vapproximately the middle of Aeach flattened area 2I so as tol form sections each including a compartment 20 in side-by-side relation to the other compartments as shown in Figure 16. .The folded flattened areas 2I' constitute extensions of the sections. Each extension is folded into overlying relation and separably secured to the extension of an adjacent section, as shown in Figure 18 at 22. To remove the articles from the package, the end-most section is torn transversely of the flattened area 2|, andsimultaneously or subsequently the strip may be torn transversely of theA flattened area close to the article containing compartment so as to open the latter and permit removal of the article.

Figures 19 to 21 inclusive show a package comprising initially separate sections B each oi' which includes an article containing compartment 23 at opposite sides of which are flattened sealed areas 24 and 25 one of which is preferably of a size approximateLvv corresponding to the size of the compartment 23. The sections are arranged in side-by-side relation with the article containing compartment 23 of one section juxtaposed to the larger flattened area 25 of the other section as shown in Figure 19. The attened portions 24 and 25 form extensions for the sections, and the extensions of each section are folded into overlying relation and separably secured to the adjacent extensions of adjacent sections, as shown at 2G in Figure 21. To remove the articles from the package, the end- Vmost section is separated from the'adjacent section and the strip is torn transversely of one of the sealed portions 24 close to the article containing compartment, as hereinbefore described.

It will be observed that in all forms of the invention the folded and overlying extension provide an approximately fiat and substantially smooth surface which makes it possible to apply a label 21 to the package as shown in Figures 14 and 15. Preferably the label' will be applied adhesively, and with the label so applied to the package, the label will assist in holding the sections of the package against separation or unfolding It will be understood by those skilled in the art that the extensions may be formed on one or more, and any edges of each section.

It will be seen that my inventionI provides an attractive v and convenient package wherein a plurality of unit compartments or sections may be secured together and handled as an entity in the form of a. block. This greatly facilitates the handling of a zigzag folded type of package,

e makes it easy to insert and remove the package respectively into and from a carton, and eliminates the possibility of hindrance and annoyance that might be caused by unfolding orseparation of the sections during handling of thev package.
